A. B. C. D.A.
To comply with fire code regulations, the technician should install plenum cable in the crawl space running the length of the hallway.
Plenum cable is specifically designed for use in plenum spaces, which are areas of a building used for air circulation. These spaces often contain HVAC systems and are used as a pathway for air to circulate throughout the building. In the event of a fire, plenum spaces can spread smoke and toxic gases throughout the building, making it imperative that any cables installed in these spaces meet certain safety requirements.
Plenum cable is designed with a special jacket that meets fire safety codes and regulations. This jacket is made of low-smoke, low-toxicity materials that release less smoke and fewer toxic gases when exposed to fire. This helps to reduce the risk of smoke inhalation and other health hazards during a fire.
Fiber, shielded, and coaxial cables are not designed for use in plenum spaces and may not meet fire safety codes and regulations. Fiber optic cables are typically used for high-speed data transfer and are immune to electromagnetic interference, but they are not suitable for plenum spaces. Shielded cables are designed to reduce electromagnetic interference, but they do not meet fire safety codes for plenum spaces. Coaxial cables are used for transmitting video signals and broadband internet, but they also do not meet fire safety codes for plenum spaces.
Therefore, the correct answer is A. Plenum.
